AI Technical Summary
The cables of the rotating parts are prone to twist, wrap and deform when there is insufficient movement space, which affects the electrical signal transmission performance and the flexible rotation of the rotating parts.
The combined structure of cantilever bracket and torsion spring is adopted. Through the elastic action of the telescopic hole of the cantilever bracket and the torsion spring, the cable remains in the "C" form during movement, and avoids "S"-shaped twisting and winding.
Effectively constrain excess length cables to prevent the cable from twisting and winding during rotation, ensuring stability of electrical signal transmission and smooth movement of rotating components.

Abstract
Description
Technical Field
[0001] The present application belongs to the field of electronic equipment structures, and in particular relates to a scanner motion cable constraint structure. Background Art
[0002] Electrical signals from rotating components are typically connected to other equipment via slip rings or cables. For rotating components with limited internal space, cable connections are the only option. When the rotating component rotates at a large angle and is close to other equipment, the cable length is longer than the shortest distance between the rotating component and the other equipment. This lacks sufficient room for movement and can lead to twisting, entanglement, and deformation. This can degrade electrical signal transmission performance and even hinder the flexible rotation of the rotating component.
[0003] Therefore, how to effectively constrain cables is a problem that needs to be solved. Utility Model Content
[0004] The purpose of the present application is to provide a scanner moving cable constraint structure to solve the problem that the cable of the rotating component is prone to twisting, entanglement and deformation when the moving space is insufficient.
[0005] The technical solution of the present application is: a scanner motion cable constraint structure, comprising a cantilever bracket, a torsion spring and a hinge seat; the hinge seat is installed on the electronic device, and a rotating shaft is provided in the hinge seat, the lower end of the cantilever bracket is hingedly matched with the hinge seat, and the upper end is suspended in the air; the torsion spring is coaxially sleeved on the rotating shaft and one end of the torsion spring is connected to the hinge seat and the other end is connected to the cantilever bracket; a telescopic hole is opened inside the cantilever bracket, one end of the telescopic hole is located at the upper end of the cantilever bracket, and the other end is located on the side wall of the cantilever bracket; the cable passes through the side wall of the cantilever bracket into the telescopic hole, and then extends from the upper end of the cantilever bracket, and is finally connected to the moving part.
[0006] Preferably, a hub is provided inside the electronic device, and the hub includes a shell, an intermediate shaft and a coil spring; the intermediate shaft is rotatably connected to the shell, and an inlet and an outlet are provided on the shell. The cable enters the shell from the inlet and is wound around the intermediate shaft, and then extends from the outlet and is connected to the cantilever bracket. The coil spring is coaxially connected to the intermediate shaft and one end is connected to the shell and the other end is connected to the intermediate shaft.

[0008] The scanner motion cable constraint structure of the present application can effectively constrain excess cable length through a cantilever structure with a hinged bracket. At the same time, the cantilever structure with an added torsion spring can always keep the cable in a "C" shape during movement, avoiding the cable from twisting and entanglement due to being in an "S" shape due to movement.

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0015] A scanner motion cable restraint structure, such as Figure 1 , including a cantilever bracket 3, a torsion spring 4 and a hinge seat 5; the hinge seat 5 is installed on the electronic equipment 6, and a rotating shaft is provided in the hinge seat 5. The lower end of the cantilever bracket 3 is hingedly matched with the hinge seat 5, and the upper end is suspended in the air; the torsion spring 4 is coaxially sleeved on the rotating shaft and one end of the torsion spring 4 is connected to the hinge seat 5, and the other end is connected to the cantilever bracket 3; a telescopic hole is opened inside the cantilever bracket 3, one end of the telescopic hole is located at the upper end of the cantilever bracket 3, and the other end is located on the side wall of the cantilever bracket 3; the cable 2 passes through the side wall of the cantilever bracket 3 into the telescopic hole, and then extends from the upper end of the cantilever bracket 3, and finally is connected to the moving part.
[0016] Combine Figure 2-Figure 3 Under the action of torsion spring 4, cantilever support 3 deflects to the right. Cable 2, after being led out from rotating component 1, passes through a free section before being tied to cantilever support 3. When rotating component 1 rotates to the right, cable 2 deflects to the left; when rotating component 1 rotates to the left, cable 2 rotates to the right under the action of torsion spring 4.
[0017] The cantilever structure with a hinge bracket can effectively constrain the excess length of the cable 2. At the same time, the cantilever structure with an added torsion spring 4 can always keep the cable 2 in a "C" shape during movement, avoiding the cable 2 from twisting or entanglement in an "S" shape due to movement.
[0018] Preferably, a hub is provided within electronic device 6. The hub comprises a housing, an intermediate shaft, and a coil spring. The intermediate shaft is rotatably connected to the housing, which has an inlet and an outlet. Cable 2 enters the housing through the inlet, wraps around the intermediate shaft, and then extends out of the outlet and connects to cantilever bracket 3. The coil spring is coaxially connected to the intermediate shaft, with one end connected to the housing and the other to the intermediate shaft. The hub facilitates cable management and effectively adjusts the extension length of cable 2 when extending or contracting, preventing excessive extension and deformation.
[0019] Preferably, a telescopic sleeve is provided within the telescopic hole, and a closed-end chute is provided on the inner wall of the telescopic hole. A plurality of balls are positioned within the chute, and the outer wall of the telescopic sleeve is connected to the balls. The cable 2 is threaded through the telescopic sleeve. As the cable 2 retracts within the telescopic sleeve, the telescopic sleeve and the balls can slide or roll with it, thereby reducing friction on the cable 2 and preventing it from getting stuck.
[0020] Finally, it should be noted that the drawings of the embodiments disclosed in this utility model only involve structures related to the embodiments disclosed in this utility model. Other structures can refer to common designs. In the absence of conflicts, the same embodiment and different embodiments of the utility model can be combined with each other.
[0021] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
